Definitions

  • the present invention is related generally to implantable orthopedic implants. More specifically, the present invention is related to implantable orthopedic bone plates used to reinforce fractured bones.
  • Orthopedic bone plates play a critical role in the healing process of broken bones. Once a bone has been fragmented, it is ideal for the broken bone fragments to be joined back together under compression to promote improved healing.
  • the bone plate is a critical device that is used as a stabilizing bar to bridge the gap between bone fragments.
  • a bone plate is inserted next to the fragmented bone of a patient.
  • Compression screws are first placed through the bone plate. They are anchored into each of the bone fragments and tightened, pulling the bone fragments together under a compression load and against the plate. Once the compression screws are set in place, locking bone screws are inserted through the bone plate and anchored into the fragmented bone.
  • the locking screws in conjunction with the bone plate secure the bone fragments together and the compression created by the compression screws ensures that they do not move.
  • high tensile stresses are created when the bone fragments are fixated with the locking screws. These tensile stresses could damage the fragile bone fragments and impair the healing process. Bone plates, therefore, are a key element in the bone healing process.
  • Bone fragmentation is unpredictable. As a result of a traumatic experience, a bone may fragment in multiple erratic locations and present itself in random orientations. Every patient's bones are unique; no two bones will fragment in the same manner in the same orientation. Nevertheless, traditional bone plate technology makes it difficult for a bone plate to be oriented in such a manner as to be utilized correctly for every trauma situation.
  • Bone plates are rigid braces, typically composed of metal, which have historically been designed with fixed threaded holes through which some bone screws may not properly align with the matching bone fragment.
  • early bone plate technology comprised bone plates with preexisting threaded holes in combination with threaded locking screws. These earlier bone plates often lacked the ability to secure bone fragments that were not aligned under the threaded screw holes. That is because the preexisting threaded holes of earlier bone plate technology confined the angle through which the locking screw could be advanced into a bone fragment.
  • an orthopedic device that expands the possible locking screw insertion angles in anchoring bone fragments to promote bone healing.
  • DE 4343117 describes a fixation system for bones comprising a bone plate with at least one bore in which is set a bone screw.
  • WO 2008/007196 describes a bone plate which is adapted for use in situ to fix a spatial relationship of at least two bone parts.
  • US 2008/234677 describes a multi-angular fastening bone screw/plate system that comprises a plate or other component suitable for affixation by a fastener.
  • US 2008/140130 describes a bone plate system for internal fixation of bone fractures which includes a bone plate having a plurality of bone plate holes.
  • the present invention is directed to an orthopedic bone plate system comprising a compression screw, a locking screw, and a bone plate with a plurality of complex locking screw apertures.
  • the inner wall of the bone plate is provided with a plurality of thread columns separated from each other by relief notches.
  • the head of the locking screw is provided with a plurality of thread columns separated from each other by relief notches.
  • FIG. 1 is a perspective view of an orthopedic bone plate system 10 according to the present invention.
  • the bone plate system 10 comprises a bone plate 12 and at least one locking screw 14. If desired, at least one compression screw 15 can also be included.
  • the bone plate 12 has a longitudinal axis A-A, an axis B-B ( FIG. 3 ) which is oriented 90 degrees from axis A-A, a bone contacting bottom side 20 and a top side 22.
  • At least one complex aperture 24 extends through the bone plate 12 from the top side 22 to the bottom side 20.
  • the complex aperture 24 is designed to receive either the locking screw 14 or the compression screw 15.
  • the complex aperture 24 is comprised of at least one set of two immediately adjacent apertures 26, 28. The apertures 26, 28 do not overlap, thereby providing the complex aperture 24 as an oval shaped opening.
  • FIG. 2 shows an enlarged perspective view of the complex aperture 24.
  • the plan view of the complex aperture 24 illustrated in FIG. 3 shows that apertures 26, 28 have a center-to-center distance d along the longitudinal axis A-A that is greater than the diameter d 1 of the head of the locking screw 14 ( FIG. 4A ) or d 2 of the head of the compression screw 15 ( FIG. 9 ). That way, the adjacent apertures 26, 28 of the complex aperture 24 define a relief-space 30 disposed between them.
  • the relief-space 30 is configured as either a straight slot, or as a constricted or "waisted" slot centered along axes A-A and bisected by axis B-B.
  • a compression ramp surface 38 emerges into the complex aperture 24 from opposite sides of the wall 34 of the bone plate 12 to provide part of the boundary for the relief-space 30.
  • the compression ramp surfaces 38 are non-threaded and ramp into the open relief space 30 of the complex aperture 24 along both the axis B-B perpendicular to the longitudinal axis A-A of the bone plate 12 and into the open space of the openings 26, 28 themselves.
  • the ramp surfaces 38 slope downwardly and inwardly from the bone plate top side surface 22 into the opening of the complex aperture 24.
  • the distal end of each of the ramps 38 meets a substantially vertical surface 40 which extends to the bone plate bottom side 20.
  • the ramps 38 meet threaded surfaces of the openings.
  • Vertical surface 40 can be planar or have a beveled contour that ramp into the open spaces 30 and into each of the apertures 26, 28 of the complex aperture 24.
  • the downwardly and inwardly sloping ramps 38 act as compression structures for the locking screw 14. As the locking screw 14 is threaded into one of the apertures 26 or 28 comprising the complex aperture 24 and moves in a downwardly direction, the underside of the locking screw head 16 compresses against the ramp surface 38. The downwardly sloping inclination of the ramp 38 causes the screw head 16 to slide down the ramp 38, creating a frictional fit and prohibiting advancement of the locking screw 14 further into the complex aperture 24.
  • the plate threads 31 are aligned in a spiral extending from adjacent to the top side 22 toward the bottom side 20.
  • the spiral of the plate threads 31 has a pitch that ranges from about 0.1 mm. to about 1.0 mm.
  • the plate threads 31 are also orientated in thread columns 32, 33, etc. ( FIGs. 6 to 8 ).
  • Each thread column 32, 33 extends along the interior aperture wall surface 34 from the top side 22 to the bottom side 20 of plate 12.
  • the thread columns 32, 33 are preferably spaced apart from each other by a distance ranging from about 0.10 mm. to about 0.500 mm.
  • each thread column 32, 33 is defined as an aperture relief notch 36 in the form of an indentation into the wall of the bone plate 12 defining the apertures 26, 28 of the complex aperture 24.
  • Each complex aperture 24 may comprise multiple relief notches 36 having exemplary shapes including curved, squared-off or as a key slot. In that manner, the threads 31 of the bone plate 12 provide both spiral and columnar structures.
  • the locking screw 14 is comprised of a bulbous head 16 and an elongated shaft 18.
  • the locking screw head 16 is comprised of locking threads that are generally indicated by numerical designation 45.
  • the threads have a pitch similar to that of the threads 31 of the bone plate 12.
  • the screw threads 45 are also aligned in a series of threaded columns 46, 48, 50, 52, etc. When viewed from the side, the locking threads 45 are separated from each other by a "V" cutout 47. It is in the space provided by the V-cutouts 47 that the threads 31 of the bone plate 12 reside as the screw 14 is threaded into the bone plate.
  • a screw relief notch 60 is provided between adjacent columns of locking threads 45. The relief notches 60 extend from the locking screw head proximal end to the locking screw head distal end adjacent to the threaded shaft 18.
  • FIG. 5 illustrates two exemplary orientations of locking screws 14 threaded in the bone plate 12.
  • the right one is at about 90 degrees with respect to the longitudinal plane of the bone plate 12 while the left locking screw 14 is at an insertion angle of about 10° in relation to the longitudinal plane.
  • Insertion angles can range from about 1° to about 45°, however, they preferably range from about 10° to about 40°, and more preferably from about 15° to about 35° from perpendicular.
  • This figure is an exemplary illustration of the many orientations that the locking screw 14 can be inserted into the bone plate 12.
  • FIGs. 6 , 7 and 8 illustrate how the present bone plate 12 and locking screw 14 system 10 allows the threads of the locking screw head 16 to bypass or "jump" threads on the bone plate. That the threads of the locking screw head 16 are capable of "jumping" threads of the bone plate 12 is made possible by the incorporation of the respective relief notches 36, 60 in both the bone plate apertures 26, 28 of the complex aperture 24 and in the locking screw head 16.
  • screw threads in column 46 and 48 reside between thread columns 32 and 33, respectively, of the bone plate.
  • the threads of the bone plate columns 32, 33 reside in the cutouts 47 provided between the thread columns 46, 48 of the screw 14.
  • screw thread 46A resides between bone plate threads 32A and 32B and screw thread 46B resides between bone plate threads 32B and 32C.
  • screw thread 48A resides between bone plate threads 33A and 33B and screw thread 48B resides between bone plate thread 33B and 33C.
  • the relief notch 36 of the bone screw 12 resides between screw thread columns 32 and 33 and relief notch 60 of the plate 12 resides between plate thread columns 46 and 48.
  • plate thread 33A is at a slightly lower elevation than plate thread 32A as the screw 16 is advancing into the bone plate. That is regardless whether the locking screw 14 is at an initial orientation perpendicular to the longitudinal plane of the plate as in the right-hand screw shown in FIG. 5 or at some other angular orientation as shown in the left-hand screw in that drawing.
  • FIG. 7 illustrates how the locking screw threads bypass or "jump" levels of bone plate threads.
  • a lateral force 100 has been applied to the locking screw head 16.
  • This lateral force 100 is illustrated by showing that the longitudinal axis of the screw 16 has deviated an angle ⁇ . This angle is measured by the difference between the longitudinal axis 102 of the screw prior to the lateral force 100 in relation to the orientation of the axis 104 after the lateral force.
  • the lateral force 100 would be imparted to the screw as the screw is simultaneously being threaded into the bone plate.
  • exemplary locking screw thread 46A has moved laterally and downwardly, bypassing or "jumping" from where it would have resided between bone plate threads 33A and 33B had the lateral force 100 not occurred to being angled toward a position residing between bone plate threads 33B and 33C ( FIG. 8 ).
  • This lateral force can only be exerted against the screw 14 when its columns of threads reside in the notches 36 of the bone plate 12. That is when the leading edge of a screw thread, for example threads 46A and 46B, is not engaged with either thread column 32 or 33 of the bone plate. However, the trailing edge of the screw threads 46A, 46B are still disposed between bone plate threads 32A, 32B and 32B, 32C, respectively. Otherwise, the bone screw 14 would be capable of simply “falling” through the bone plate every time the columns of threads 46, 48, 50, 52, 54, etc. on the screw 14 are in alignment with the relief notches 36 of the plate 12.
  • each thread 45 comprising the thread columns 46, 48, 50 52, 54, etc. of the screw 14 are laterally from about .5 to 2 millimeters wider than the width of the bone plate relief notches 36.
  • exemplary screw thread 46A has its leading edge just beginning to reside between the edges of plate threads 33B, 33C before the trailing edge of that thread has left the edges of plate threads 32A, 32B. That is from a longitudinal perspective with respect to the edges of the threads of the plate 12 and of the screw 14 as shown by dashed lines 106 and 108.
  • the present plate and screw system 10 permits the physician to change the angle of the screw 14 part way through it being screwed into the plate 12, that should not be viewed as limiting.
  • the screw 14 could be oriented with the threads of the bone plate 12 in the orientation shown in FIG. 8 . That is in a "jumped" or cross-threaded orientation from the beginning.
  • the sequence of drawings of FIGs. 6 to 8 shown that the angle ⁇ can be increased so that the screw ends at a greater angle of inclination that which it was first oriented ( FIG. 6 ), the angle could also be decreased.
  • the compression screw 15 illustrated in FIG. 9 can also be used with the bone plate 12 of the present invention.
  • the compression screw 15 has shaft threads 15A that are helically disposed around the shaft 15B.
  • An unthreaded head 15C is affixed to the proximal end of the shaft 15B.
  • the bone plate 12 and locking and compression screws 14, 15 are preferably made from Ti 6A1-4V.
  • other biocompatible materials not limited to other titanium alloys, stainless steel or polymers, i.e., PEEK could also be used.
  • FIG. 1 further illustrates that the bone plate can comprise a threaded aperture 110 adapted to receive only one screw or an overlapping threaded aperture 112.
  • the overlapping threaded aperture is similar to that described in U.S. Patent No. 7,695,472 to Young .
  • the complex aperture 112 comprises at least two overlapping holes having an offset of a given distance between centers thereof, wherein any two immediately adjacent overlapping holes comprise a compression ramp extending from an oval shaped opening at the top side of the plate downwardly and inwardly part way through the plate thickness to a threaded lower portion having an hourglass shape extending from where the compression ramp ends at the hourglass shape to the bottom side of the bone plate with threaded surfaces of the overlapping holes meeting each other at a threaded overlap forming the hourglass shape, wherein the threaded lower portion is adapted to lock with threads of a corresponding bone screw in one or the other of the overlapping holes.
  • the overlapping holes can be formed either normal to the top side of the plate or at an angle offset from normal. In either embodiment 110, 112, the aperture has a relief notches disposed between columns of threads as described with respect to the complex aperture 24.
